glxinfo from guest

Hi!

I was testing virgl on nv50 and llvmpipe. It was working last year, showing
OpenGL 3.3 in Linux guest. Now it only displays OpenGL 2.1 [but still works]

 LIBGL_ALWAYS_SOFTWARE=1 qemu-system-x86_64  -enable-kvm -m 1G -display
sdl,gl=on -soundhw es1370 -cdrom /mnt/sdb1/slax-14_06_2019-private0.iso -vga
virtio -usbdevice mouse -smp 3 -cpu max
qemu-system-x86_64: -usbdevice mouse: '-usbdevice' is deprecated, please use
'-device usb-...' instead
gl_version 33 - core profile enabled
Mesa: User error: GL_INVALID_VALUE in glTexImage2D(internalFormat=GL_ALPHA8)
Mesa: User error: GL_INVALID_VALUE in glTexImage2D(internalFormat=GL_ALPHA16)
GLSL feature level 330

In guest:
